disp: msm: dp: clear link info capabilities during DP disconnect

This change clears all link info capabilities as a part of
panel deinitialisation during a disconnect sequence. Without
this change, the link info capabilities like the CRC flag will be
retained for the next hotplugged device. Now if, a MST is connected
after a SST connection, the base panel will have the CRC value of the
previous sink, which will be invalid for the case when the hub doesn't
support CRC.
